Symptoms of Colon and Rectal (Colorectal) Cancer

Symptoms of colon and rectal (colorectal) cancers may resemble other conditions, such as infections, hemorrhoids and inflammatory bowel disease. Individuals may experience symptoms differently and in some cases, no symptoms will be present. The most common symptoms of colorectal cancer include:

  • A change in bowel habits, such as diarrhea, constipation or narrow stools that lasts for more than a few days
  • A feeling that you need to have a bowel movement that is not relieved by doing so
  • Rectal bleeding, dark stools or blood in the stool
  • Cramping or gnawing stomach pain
  • Decreased appetite
  • Vomiting
  • Unintended weight loss
  • Weakness and fatigue

If you are experiencing any of these symptoms, ask your physician if you should be screened for colorectal cancer––especially if you are over 50 years old or have a personal or family history of cancer.
